The anterior acrylic resin platform and centric relation verification: A clinical report

Abstract

Diagnostic casts mounted in centric relation are essential in comprehensive diagnosis, treatment planning, and predictable restorative procedures. Dawson’s bimanual manipulation, to locate centric relation and to confirm this position of the condyles in the glenoid fossae with load testing, has been detailed. 1 Dawson PK Evaluation, diagnosis, and treatment of occlusal problems. in: 2nd ed.

Int J Periodont Restorative Dent. 1985; 5: 11-30 Google Scholar A light touch is initially used to guide the mandible into centric relation, followed by increasing increments of force to perform the load test. This approach is designed to avoid protective muscle bracing initiated by the stretch-reflex mechanism that could alter the anterior-posterior or medial-lateral position of the mandible; or confuse load testing pain in the lateral pterygoid muscle with intraarticular temporomandibular joint (TMJ) pain.
